Stuart,
thanks for the quick reply. I am going to assume that /dev/sda2 is my root
filesystem - right?
--- snip ---
$ df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 151723100 3861340 140154580 3% /
/dev/sda1 101089 35938 59932 38% /boot
none 512700 0 512700 0% /dev/shm
--- snip ---
now my /etc/fstab looks like this:
--- snip ---
/dev/sda2 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/sda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom udf,iso9660
noauto,owner,kudzu,ro 0 0
--- snip ---
cheers,
Noah
